Bait known that 1, Bosnia F. Warmer, a citizen of the United States, andresident of Winchester, in the countyof Middlesex and State of Massachusetts, have invented useful Improvements in of which the folcertain new and Hide-Working Machines, lowing 1s a specification.

This invention relates to that class of ma- 4 chines for fie'shing, unhairing and working hides and leather, in which the hide is placed over a movablebed roll, by which it is carried into contact with the work roll i mounted on shaft 21,

and supported while being treated by said work roll; and its object is to ranged that ample room is provided for introducing the hide into the machine.

The invention is illustrated by'the accompanying drawings in which- Figure 1 is a side elevation of the machine looking fro nthe left of Fig. 2. Fig. 2 is a front elevation of the machine. ig. 3 is a detailed view of the table and its connections. Fig. 4 is a modification of Fig. 3 showing a plurality of tables.

Similar characters refer to similar parts throughout the several drawings.

The main frame of the machine consists of side frames 1 connected by tie girts 2. Work roll 3 is mounted on shaft 4 journale'd in the frame. Bed roll 5 is mounted on shaft 6 journaled in swinging arms 7 fulcrumed on studs 8 fixed to the frame. Feed roll 9 is mounted on shaft 10 journaled in swinging boxes 11 fulcrumed on studs 12 fixed to the frame and pivoted at 13 to spring-controlled rods 14 slidingly mounted in the frame. Table 15 is fixed to swinging arms 16 fulcrumed on shaft 6 of bed roll 5.

Rollers 17 are mounted in longitudinally adjustable swin ing arms comprising upper members 18 sli ingly engaging lower members 19 and furnished with springs 20 which act as cushions for said rollers 17; said members 19 being fulcrumed on studs 8.

This table 15 may be made of an desired form and material, but is prefera ly made of cast iron and in the form of a box which is furnished interiorly with a series of transverse springs 15", which form a cushion for the top of said box which preferably consists of a yielding covering, such as leather or rubber.

provide an so that the In Fig. 4 is shown a modification of the machine embodying a plurality of tables, namely, table 15 fixed to the swinging arms 16" and table 33 pivoted at 33 to said swinging arms 16 and resting on the studs 33 mounted longitudinally adjustably on said swinging arms 16. Eccentrics 7, mounted on shaft 21, are pivoted to toggles 22 whose inner' links are pivoted at 23 to swinging arms 7 and whose outer links are pivoted to rockers 25 pivoted at 26 to the frame and at 27 to spring-controlled rods 27 slidingly mounted in the frame. Eccentrics 19, engage and operate swingin arms 1819. Shaft 21 is mounted in the rame and furnished with a gear 28 through which it is rotated by clutch 29 mounted on shaft 29 fixed in the frame, the driving member of which clutch is furnished with gear 29 through which and intermediate gearing it is actuated by pulley 30. The clutch is operated by treadle 31 mounted on shaft 21 and connected with the clutch mechanism by chain 31. operated by pulley 32 fixed to its shaft. The clutch mechanism employed to rotate shaft 21 and the gears employed to rotate the bed roll are shown but need not be described as they form no part of the present invention, which lies entirely in the combination of the work roll with the table, or tables, and bed roll, described, irrespective of the means employed for bringing these parts together and separating them.

The operation is as follows: Normally, when inoperative, the table 15 and bed roll 5 are in the position shown in dotted lines Fig. 3, providing ample room for the insertion of the hide the work roll 3 is being driven through pulley 32; the feed roll 9 is at rest; and the driving member of the clutch is being 30. After inserting the hide, the operator depresses treadle 31, thereby engaging the clutch members, actuating the eccentrics and bringing the operating parts together as shown in full lines Fig. 3. When the rolls are together, bed roll 5 is rotated by the gearing shown, but not described, and feed roll 9 is rotated frictionally. As soon as the operating parts are brought together, the clutch members become automatically disengaged, leaving the operating parts together, until the operator again depresses the treadle, when the clutch operates to separate the operating parts and thereupon The work roll is driven through the pulley- Q Losses? again becomes automatically disengaged The operation is similar when a plurality of tables is employed, as shown in Fig. 4.

By the improvement described, work is done upon the hide or leather along the lines where it passes between the work roll and the table, or tables, and where it passes between the work roll and the bed roll, and this is the principal feature of'my invention; but, as will be readily seen, by this arrangement a portion of the hide or leather is held tightly wrapped around that part of the Work roll which extends between said contacts with the table, or tables, and bed roll, so that effective work is also done on that portion of the hide. The machine is particularly adapted to unhairing and working out different hides and skins and also to putting out or setting leather in the different stages of manufacture.

Having described my invention what- I claim and desire to secure by Letters Patent is:

1. In a machine of the character described, in combination, a work roll; a bed roll having a shaft journaled in swinging arms; and a table fixed to swin 'ng arms fulcrumed on said bed roll sha t; said bed roll and said table bein movableinto and out of contact with saif work roll; with means for accomplishing said movements; substan-. tially as described.

2. In a machine of the character described, in combination, a work roll; a bed roll having a shaft journaled in swinging arms; and

7 arms fulcrumed on said bed roll shaft; sai

a plurality of tables mounted on bed roll and said tables being movable into and out of contact with said work roll; with means for accomplishin said movements; substantially as describe v 1 3. In amachine of the character described, in combination, a work roll, a bed roll and a table; said bed roll and said table being simultaneously movable into and out of contact with said work roll; with means for accomplishing said movements; substantially as described.

4. In a machine of the character described. in combination, a work roll, a bed roll and a plurality of tables; said bed roll and said tables being simultaneously movable into and out of contact with said work roll; with means .for accomplishing said movements; substantially as described.

5. In amachine of-the character described, in combination, a. work roll, a bed roll, a table and a feed roll; said table being movable into and out of contact with said work roll; said bed roll being movable into and out of contact with said work roll and said feed roll; with means for accomplishing said movements; substantially as described.

In testimony whereof I have aflixed my signature, in presence of two witnesses.
